I like coffee very much 
But I can’t sleep well lately...
I had a hard time falling asleep last night 
So I took a medicine.
It happened on Tuesday . I think...
I tend to think deeply about work on Tuesday night.
“ tomorrow will be so hard “ etc.
If I can’t sleep, l won’t be able to work hard 
That’ll make it even harder for me to fall asleep 
And should I quit drinking coffee
That’s why I can’t concentrate on works
